How do I drop the fuel tank on a 1993 Nissan Altima?
My 1993 Nissan Altima was leaking Gas from where the fuel lines come off the tank (out of view) when he turned on the ignition. the car would run fine but still leaked gas (a large amount). I tried to drop the tank but it is held up by the exhaust system as far as I can tell. Since that would cause more problems, I was hoping to get some suggestions.

If you mean the fuel line,start the engine, then remove the fuel pump relay , when not enough fuel pressure to run the engine, it will die and line will be depressurized. The tank itself only has minimal pressure which is vented. Removing the filler (gas) cap will relieve any excess pressure in the tank...Mike
Fuel pump is a complete assembly set inside the fuel tank. You'll need to drop the tank, (you might want to remove the gas FIRST) unplug the wiring, disconnect battery, all fuel, return, and vapor lines, etc. You should get someone experienced if this is your first time. It's a big job.
MOST fuel filters are either prior to the entrance to the fuel pump on the fuel line, OR under the vehicle attached to the framework, follow the fuel line from the top of the gas tank until you locate the filter receptacle...
Turn the key to on, and listen under the car to see if you can hear the fuel pump running. or you could take a rubber mallet and tap the bottom of the gas tank while someone is turning the ignition over. I would almost bet you have a faulty fuel pump.
